I would like to disable local access/changes to an HAI Omnistat RC-80 thermostat. Physical location is 2nd story. Thermostat will only be used to monitor current/outside temp. Temperature changes/adjustments to be made via console control keypads. I have teenage son that enjoys raising temperature to roasting levels in morning while other members suffer. I believe there used to be a technical bulletin or application note on removing or adding a jumper to board, but can not find when I could use it. Anyone have this helpful info or where located?
